摘要： A misfire detecting device for a double-ended distributorless ignition system is provided. The device includes a pulse generating circuit for generating a positive polarity pulse which is not so high as to cause spark discharge during the time after completion of spark discharge and before beginning of application of an ignition high voltage for next spark discharge. A reverse current preventing diode is connected at an anode to an output end of the pulse generating circuit and at a cathode to a positive polarity side of a secondary winding of an ignition coil. A plug voltage dividing circuit for dividing a plug voltage is connected between a center electrode and an outer or ground electrode of each of spark plugs to obtain a divided voltage. A detecting circuit detects a misfire of the spark plugs on the basis of an attenuation characteristic of the divided voltage after application of the positive polarity pulse.

摘要： In a misfire detector device for internal combustion engine, an ignition coil is provided to be on-off actuated by a primary current interruptor circuit, each end of the ignition coil being connected to a spark plug installed in each cylinder of an internal combustion engine. A peak voltage detector circuit detects a peak voltage applied across the spark plug electrodes after an end of spark action of the spark plug. A peak voltage value distinction circuit recognizes a misfire when a voltage level exceeds a predetermined level which is detected by the peak voltage detector means after an end of spark action of the spark plug upon running the internal combustion engine at a high speed. A distinction circuit recognizes a variation of angles detected by the crank angle sensor so as to determine the misfire when the variation of angles exceeds a predetermined value upon running the internal combustion engine at a low speed.

摘要： An air/fuel ratio detection device and an air/fuel ratio control device, in which combustion of an engine is controlled with a simple design and toxic substances in exhaust gas discharged from the engine are reduced. Time A during which a lean signal is at a high level is measured. If the time A is shorter than the predetermined value, it is determined that the air/fuel ratio is richer than a target value, and time B during which an electromagnetic valve 21 is open is lengthened, increasing the quantity of supply air and making leaner the fuel mixed air, such that the target air/fuel ratio is approached. If the time A is longer than the predetermined value, it is determined that the air/fuel ratio is leaner and the time B is shortened.

The distance between the photo diode and the light emitting diode and the width dimension of the photo diode are determined such to provide incident angles ranging from a minimum corresponding to the critical angle when the mixing liquid ratio is at lower limit of the predetermined range to a maximum corresponding to the critical angle when the mixing liquid ratio is at upper limit of the predetermined range.
